An emergency flight

PALLONCINO AND PALLONCINA ARE FLYING WITH AUNTIEBALLOON AND UNCLEBALLOON WHEN SUDDENLY, OUT OF NOWHERE, A CRY OF PAIN CATCHES THEIR ATTENTION. AN ACHING HOT-AIR BALLOON, ASSISTED BY RESCUE BALLOONS, WILL MAKE THE SMALL HOT-AIR BALLOONS GLOOMY. AUNTIEBALLOON AND UNCLEBALLOON WILL HELP PALLONCINA AND PALLONCINO REALIZE HOW THEY CAN REALLY BE OF ASSISTANCE TO THAT ACHING HOT-AIR BALLOON.
